Last updated date：2022/7/26
Overview of the first and second vaccination shots (for residents 12 and older)
Who is eligible?
Residents 12 years old and older.
Guardian’s consent is required for individuals age 12-15 to get the vaccine
The vaccine may be administered with consent of the individual’s guardian for those ages 12 to 15. The vaccination cannot be administered without the guardian’s signature on the vaccination pre-screening questionnaire. Also, the guardian must accompany the individual.
From February 17, 2021 through September 30, 2022 (planned)
Vaccines used by age group and intervals between doses
Two shots are required to complete the first vaccination.
|Vaccine||Waiting period between the two doses||Eligible age group|
|Pfizer||3 weeks||12 and up|
|Takeda/Moderna||4 weeks||12 and up|
|AstraZeneca (*1)||4-12 weeks (*2)||40 and up (*3)|
|Takeda (Novavax)||3 weeks||12 and up|
*1 Used at Kanagawa Prefecture vaccination venues.
*2 In order to achieve maximum efficacy, a waiting period of eight weeks between shots is recommended.
*3 People 18 and up may receive the vaccine if deemed necessary.
Waiting period between first and second shots
Even if you have passed the standard waiting period between shots, you can receive your second shot. There is no upper limit for how long you can wait between shots. There is no need to start over and receive your first shot again, so it is recommended that you get your second shot as quickly as possible.
Although the efficacy of the vaccination after passing the standard waiting period has not been thoroughly tested, as a guideline, the World Health Organization (WHO), the United States, and some countries in the EU recommend getting the second shot within 6 weeks of the first shot, even if it has been longer than 3 weeks (for the Pfizer vaccine) or 4 weeks (for the Takeda/Moderna vaccine).
The individual’s age group depends on how old they will be on the day of the vaccination.
Vaccinations will be administered using public funds, and are free of charge for everyone.
*However, there is a possibility you will have to pay for doctor fees if you visit a clinic before or after the vaccination.
Mixing vaccination types
While you are generally required to receive the same type of vaccine for both of your first and second shots, in some cases you may be allowed to receive a different type for your second shot (mixed vaccinations). See this page for more details. See this page（外部サイト） for more details.
Potential side effects after getting the shot (side reactions)
The COVID-19 vaccines have been seen to sometimes cause side effects after they are administered, such as pain around where you were given the shot, headaches, fatigue, muscle and joint pain, chills, diarrhea, or fever. Recipients will recover within a few days of receiving the vaccine.
